Specification of Letters Patent.

Patented March 9, 1909.

Serial No. 409,062.

To all whom it may concern:

Be it known that 1, Ounrrs W. DAvrs, of Donaldson, Kittson county, Minnesota, have invented certain new and useful improvements in Hay-Stackers, of which the following is a specication.

My invention relates to machines for transporting to a stack.

The object of my invention is to provide a machine of comparatively few parts, easily operated and very eflicient for the purpose designed.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

1n the accompanying drawings forming part of this specification, Figure 1 is a plan view of a stacker embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation. Fig. 4 is a sectional view illustrating in detail the mechanism for lifting the fork from the axle.

1n the drawing, 2 represents an axle having carrying wheels 3.

4 is a frame extending rearwardly from the middle portion of the axle and supported at the rear end by a wheel 5 which has a post 6 journaled in said frame and an operating handle 7 by means of which a person in charge of the machine, standing on the platform 8, may guide it across the iield. An evener 9 is mounted on the frame in front of said platform to which swingletrees 10 are attached on each side of the machine. These swingletrees are capable of adjustment on either side of the evener so that the team may be driven ahead or swung around to the other side of the evener to draw the machine backward.

Mounted on the axle 2 are side standards 11 at each end of the axle and a pair of middle standards 12 upwardly from the middle portion of the axle. These standards are connected with the top of the machine by a cross bar 13. Between the middle standards 12 a beam 14, pivoted at 15 between standards 16 on the frame 4, is adapted to slide. A fork head 17 is pivoted on the forward end of the beam 14 and is provided with a series of forwardly projecting tines or teeth 18 whose extreme rest upon the ground. Braces 19 connect the said head with the beam 14 and brace the fork against oscillation. Oables 20 are athay from different parts of the Ylield forward ends are adapted to s l fork overhangs the stack and tached to a cross-bar 21 extending transversely of the tines 18 near the head 17, and extend up over sheaves 22 on the cross-bar 13 and from thence to drums 23 provided on the axle 2 on each side of the center. These drums have clutch connections 24 with the carrying wheels and are adapted to slide on the axle toward and from the heads of said wheels for the purpose of rendering the clutch devices operative or inoperative. Braces 25 connect the ends of the axle with the frame, and bars 26 are pivoted on said braces and have their forward ends loosely connected with the drums 23. Toggle links 27 are pivotally connected to said bars at one end and at their opposite ends to a block 28 that is adapted to slide between guides 29 on the frame. A rod 30 is attached to said block at one end and at the other end to an operating lever 81 mounted on one of the standards 16 within reach of the attendant on the machine. By moving this lever back and forth from its quadrant the block 28 will be operated and through the toggle links to force the drums out into engagement with the clutches on the carrying wheels or withdraw them. These drums operate continuously when the machine is in motion, assuming that they are in operative position and the cables will be wound thereon to lift the fork and its load.

A bail 32 is attached to the cross bar 21 and extends up over the head 17 of the fork and is pivotally connected to a rod 33. The rear end of the rod has a chain 34 attached thereto that is adapted to be wrapped around a shaft 35 journaled in the standard 16. This shaft has a suitable operating wheel 36 and a ratchet mechanism 37 by means of which the tilting of the fork may be controlled. The upright standards are connected with the standards 16 at the rear of the machine by braces 38. A receptacle 39 is mounted on the rear of the machine in which suitable material may be placed for weighting that end of the machine to counterbalance the load on the fork.

In the operation of the machine the hay or other material to be stacked is raked on to the fork or gathered up by means of poles and deposited thereon. When the fork is full the drums are thrown into mesh with the carrying wheels, the machine is started and the fork raised to the position indicated by dotted lines in Fig. 2. When the stack is reached the machine is driven up so that the the attendant end on said axle,

3f. A machine of the class described, comprising` an aXle, and carrying` wheels therefor, a frame supported at its forward end on said axle and extending rearwardly thereirom, a platform mounted on the rear end of said tram-e, a swiveled guiding: wheel supporting the rear of said frame and. said platform,` standards mounted on said frame in front. of said platform, a beam pivoted at itsrearendto said standards and above said frame andY ro1 jecting forwardly therefrom over said ax e, a forl pivotally supported on the for-Ward end or said beam, a drum mounted, between Liter-hedy to said fork on each side of' the ,platform standards and having; a Cable een center thereof, and passingI over pulleys on ,l nection with said fork, standards mounted each side of the center of said cross: bar at y on said axle there beingone at each end the top of, said standards and winding` drums, j thereof and two. near the middle and a, cross mounted on said axle connected with bar connecting all the said standards at. the said cables; and means for rendering;` said top, said beam being vertically slidable bee. drums operative or inoperative, substan tween, said middle standards, cables attached tally as described., te said fork oneach side ofthe center thereof A machine of the class described,l coml and passi-ngover the pnlleys provided on said prism-g a. forward cross. bar an drums mounted on each end oi tl-ierefor, a frame sup-ported at. lts forward I said shaft and connecting with said` fork caend on said axle, means supporting the rear i bles, and means. for rendering said drum-s end of said frame, standards. mounted on said operative or axle, there being one at each end thereof and l scribed.. two near the center, said center standards l In witness whereof, I have hereunto set being comparatively near together, a cross i my hand this 23rd day of December 190,-7., bar-connecting all the said standards, a beam C, W DAVS pivot-'ally supported at its rear end and then slackens the chain 34 to allow the fork tached to said fork to tilt down sufficiently to rest upon the f stack.
